So if you’re looking to buy a new pair of running sneakers, On Running might just be the brand for you. The fit of your shoes is always important, but maybe even more so for your running sneakers. Having ill-fitting shoes can result in painful blisters, muscle pain, and even injury. So to make sure you can keep on running – check out our handy size guide to help you find the perfect running shoe! We divided the size guide into four different sections based on the four different types of running shoes from On Running, 1) road running 2) trail running 3) racing  and 4) waterproof and all-weather.

On Running road running shoes are designed for comfort and performance when you’re running on paved surfaces. They feature the brand’s signature CloudTec cushioning system and often incorporate a Speedboard for enhanced energy return.

• Cloudstratus 3: The Cloudstratus 3 is known for its maximum cushioning with a double layer of Cloud elements. It provides a smooth and stable ride – which is ideal for both short and long runs. This model tends to fit true to size with a comfortable, secure fit.

• Cloudmonster: The Cloudmonster is designed for long-distance running with a rocking profile that propels the runner forward. It offers a comfortable fit with a soft sock lining and a large toe box, making it suitable for runners with various foot shapes. The Cloudmonster fits true to size.

On Running trail running shoes are engineered for off-road adventures, featuring enhanced grip, protection from terrain, and stability. They often incorporate the brand’s Missiongrip technology for traction on various surfaces.

• Cloudultra 2: The Cloudultra 2 features the highest amount of cushioning among On’s trail shoes. It includes lugs for grip and a shifted pod setup to reduce rock catches. This model tends to fit true to size, but may feel snug for wider feet.
  

• Cloudvista: The Cloudvista is a run/hike crossover shoe that handles various terrains. It includes a built-in lace loop and On’s Missiongrip for excellent traction. This model generally fits true to size with a comfortable, secure fit.

Running a marathon? Need an extra leg-up from the competition? On Running racing shoes are optimized for speed and performance during races. They often feature lighter materials and advanced cushioning technologies, including carbon fiber plates in some models.

• Cloudboom Echo 3: The Cloudboom Echo 3 is designed for pure speed, featuring a unique rockered shape and a snappy rigid carbon plate. This model is known to run extremely narrow and is not recommended for runners with medium to wide feet.
• Cloudflow 4: While not exclusively a racing shoe, the Cloudflow 4 is often used for speed work. It offers moderate cushioning and a lightweight design. This model tends to fit true to size but may be narrow for some runners.

On Running waterproof and all-weather shoes are designed to endure various weather conditions. If you’re a rain or shine kind of runner, or maybe you like to run out your feelings in the pouring rain, or maybe you just live in place that usually has rainfall in the weather forecast – it’s a good idea to invest in some sneakers that can hold up in wet conditions. On Running’s weatherproof shoes features waterproof membranes and enhanced grip for wet surfaces to keep you from slipping.

• Cloud 5 Waterproof: The Cloud 5 Waterproof is designed to block water and wind while providing grip on wet surfaces. This model may fit slightly snugger than its non-waterproof counterpart, so consider sizing up by half a size for the best fit.

• The Cloudflyer Waterproof 2.0: The Cloudflyer Waterproof sneaker 2.0 ensures dry feet in harsh weather conditions, with a focus on grip and comfort. Like other waterproof models, it may run slightly small, so consider sizing up for the most comfortable fit.
